study (v.)

early 12c., studien, "to strive toward, devote oneself to, cultivate" (virtue, vice, wisdom, art, etc., sometimes translating Latin occupare), from Old French estudiier "to study, apply oneself, show zeal for; examine" (13c., Modern French étudier).

This is from Medieval Latin studiare, from Latin studium "study, application," originally "eagerness," from studere "to be diligent," which is reconstructed to be from PIE *(s)teu- (1) "to push, stick, knock, beat" (see steep (adj.)). The notion appears to be "pressing forward, thrusting toward," hence "striving after."
